The MS5839 is a digital OEM sensor that measures the absolute pressure with high resolution. It is compensated and outputs the measured values as digital output signals via an I²C interface.
The reflowable sensors are designed for the pressure range of 300 – 1200 mbar (MS5839-02BA36) and are media-protected with a chlorine resistant gel coating. They are also shielded. In addition to the pressure, they measure the temperature from -40 to 85 ° C.
The MS5839 pressure sensors consist of a piezoresistive pressure cell and an amplifier A/D-interface-IC, housed in a QFN package (3.3 x 3.3 x 2.75 mm³). The metal top protects the electronic components and facilitates O-ring mounting. The sensor converts the measured pressure- and temperature-dependent signal of the measuring cell into a 24-bit data word. The I²C interface is used for serial communication with the microprocessor.
The sensors are intended for applications with a digital system environment. Since there is already a processor at system level, this can be used to easily calculate the current pressure and temperature values.
